Psoriasis Diet: What to eat & What to avoid

If you’re living with psoriasis you may have wondered how food affects your skin – or you might feel that some foods seem to make your psoriasis worse.

But what does the science say?

What do we know about diet and psoriasis?

Understanding how diet affects psoriasis is complex, because we don’t eat single foods by themselves, but a mixture of foods in meals, so separating the effects of one food from another is tricky.

It’s also hard to detach the effects of food from some of our other habits. For example, in the 1980’s scientists thought they had found a link between coffee and psoriasis, but they later realised people who drank lots of coffee were also more likely to smoke, and when they separated coffee drinking from smoking, the link disappeared.
